10 Foresight allowed Nighteye to see the future

Sir Nighteye was once All Might's sidekick and now runs his own Hero Agency. Not just anyone could stand alongside All Might in his prime, but with a Quirk like Foresight, it's quite easy. Foresight allows Nighteye to see anyone's future for up to an hour (at his discretion). For the most part, his visions are infallible. But Izuku Midoriya proves that his visions are only probable futures, not certainties.

Even so, Foresight is an indispensable tool for reconnaissance and knowing when an opponent is about to attack. With Foresight, Nighteye can predict villains' movements and act accordingly. Nighteye sadly loses his life in season 4 of My Hero Academiabut the memory of his incredible Quirk is a testament to how essential he was.

9 Dark Shadow is somehow sentient

Dark Shadow is one of the most interesting Emitter Quirks, as sentient life seems to emanate from it. Fumikage Tokoyami has Dark Shadow bonded to him, but Dark Shadow has its own thoughts and emotions. Dark Shadow's true nature is never explained, but there are a few things fans learn about this Emitter Quirk as the story progresses. The most important part about Dark Shadow is that it is easier to control, but weaker, in light.

It's much more powerful (and dangerous) in the dark. Tokoyami works hard to gain the strength to control Dark Shadow in the dark, but it takes a lot of training. Tokoyami also discovered a way to make Dark Shadow act like wings so he can fly. There are still many mysteries surrounding this Quirk, but that's what makes it one of the most dynamic Emitter Quirks.

8 Erasure is an invaluable peculiarity

Shota Aizawa's Quirk isn't flashy, but it's one of the most useful and powerful. Aizawa's Quirk is Erasure. With it, he can cancel anyone's Quirk, as long as he makes eye contact with them while activating it. As long as Aizawa keeps his eyes fixed on his opponent, their Quirk will remain canceled.

The downside to this Quirk is that Aizawa's eyes dry out regularly, and if he blinks, the person's Quirk returns to them. Aizawa has become proficient at pushing his limits to keep villains' Quirks in check, but he's not perfect. Even so, Erasure is one of the most useful Quirks to have—especially against someone with a particularly strong Quirk.

7 Half cold half hot is as versatile as it is powerful

Shoto Todoroki is one of the luckiest people in terms of Quirk manifestation. Instead of receiving just one Quirk from one of his parents, or a combination of them, Todoroki received Quirks from both parents separately. Todoroki's Half-Cold Half-Hot Quirk gives him the power of both fire and ice. His right side was built to resist and produce immense amounts of ice, while his left side was designed to resist and create enormous flames. Todoroki avoided using his Fire Quirk for a time, but has since embraced his full Quirk.

Half-Cold Half-Hot gives Todoroki a wide range of attack options. Not only can he fight with either element, but he can also combine his powers into a deadly force. He has the advantage of using either side to regulate his temperature, preventing him from getting too cold or overheating. Todoroki is also known for using his ice as a shield and a slide for agility. Both sides are useful during almost any battle, making Half-Cold Half-Hot as versatile as he is powerful.

6 Bloodcurdle interrupts its victims

Bloodcurdle allows The Hero Killer: Stain to paralyze his victims for a period of time after ingesting their blood. The paralysis lasts longer depending on the blood type. Stain initially uses this fearsome Quirk to immobilize Pro Heroes before killing them in the name of purifying the Hero Society. Later, however, Stain becomes a vigilante and fights for the Heroes. Bloodcurdle—like Erasure—seems to be an indispensable tool in battle.

As long as Stain can ingest someone's blood (which seems likely in a fight), he can paralyze them just enough to easily secure victory. After all, there's a reason he's been able to subdue and dispatch so many Pro Heroes during his attacks. The Heroes are lucky he eventually sides with them because his Emitter Quirk is one they wouldn't want to face alone.

5 Brainwashing allows Shinso to control minds

Hitoshi Shinso has one of the most literally influential Quirks in the series. His Brainwashing Quirk allows him to control anyone as soon as they respond to him. Many fear this power, but Brainwashing only works if Shinso chooses to activate it. Even so, Brainwashing has virtually unlimited potential, as long as its target simply responds to Shinso.

Knowing that people would eventually realize the need to respond to his Quirk, Shinso now uses a voice modulator during battle to mimic others' voices. This way, he can capture his targets by pretending to be someone else. Brainwashing is a Quirk so powerful that it even unlocks One For All and Midoriya's previous users. It's no wonder Shinso was automatically placed in the General Studies Course without considering how immensely powerful his Quirk is.

4 Backtracking is difficult for Eri to control

Rewind is a surprising Quirk for a seven-year-old girl, but Eri wields it with courage. This incredible Quirk has the power to rewind someone to any point in their life they've ever experienced. Any moment between the last second and the beginning of life is fair game when it comes to Rewind. Unfortunately, because of her young age and her captivity at the hands of Overhaul, Eri hasn't yet fully mastered her Quirk.

She's working closely with Aizawa to learn about it, but her emotions play a significant role in her ability to wield Rewind. Fortunately, Eri is becoming more confident in using her Quirk and even helps Mirio Togata regain his lost Permeation Quirk. Eri still has a long way to go, but there's no denying how powerful her Rewind Quirk is.

3 Explosion suits Bakugo's personality

Katsuki Bakugo is one of the strongest and boldest students in My Hero AcademiaThis is partly due to his indomitable Quirk, Explosion. The explosion is the result of the combination of Bakugo's parents' Quirks. With his Quirk, Bakugo can create explosions by igniting his nitroglycerin sweat. Over the years, Bakugo has honed his Quirk so much that he can create a concentrated blast and can also use his Quirk for mobility.

Because of Explosion's power (and his personality), Bakugo is often seen as more of an antagonist than a hero. However, Bakugo proved his naysayers wrong. Bakugo uses Explosion to blind and knock down enemies that would otherwise cause irreparable damage. Explosion isn't the stealthiest Quirk, but it makes up for it with sheer, unbridled power.

2 Decay is the most devastating

Tomura Shigaraki's decline is the most devastating Quirk in My Hero AcademiaAnything he touches while his Quirk is activated will immediately disintegrate. Now that he's awakened his Quirk, Shigaraki's Decay is spreading, causing things adjacent to anything he touches to begin to decay as well.

Decay was tragic before Shigaraki's Quirk awakened, and now it's utterly desperate. With a single touch, Shigaraki decimates the city of Deika. Decay is one of the strongest Emitter Quirks because of the utter destruction it brings. If not used carefully, Decay could destroy society as we know it. Unfortunately, this unyielding power is in the hands of a villain. It's up to the Heroes to fight this Quirk and end Shigaraki's reign of terror.

1 One for all has been passed down through generations

One For All is perhaps one of the strongest Quirks in the My Hero Academia universe. With each successive user, it combines their current abilities to create a Quirk so powerful that it requires extreme training to use. Furthermore, once granted to Izuku Midoriya, it imparts the Quirks of the previous users—essentially turning him into a charitable All For One.

One For All holds many mysteries that even All Might is still figuring out. However, even without knowing everything about it, One For All is still incredibly powerful. Users of this Quirk can destroy enemies with single strikes, and Midoriya has learned how to use it to empower his leaps to move in combat. It's no wonder All For One desires this Quirk so much, considering how much raw energy is stored in a single Quirk.
